Abstract: 19,232. Hõllgren, C. A. V. Aug. 27. Wiring.-Relates to a machine for wiring corks or stoppers in bottles, flasks, &c., and provides means for firmly holding the bottle, and for preventing any displacement of the parts which guide, twist, and cut off the wires. The wiretwisting means comprise a ring 7, Figs. 1, 4, and 5, mounted between, and guided at its periphery by, rollers 8 carried by the machine frame. The ring is provided with teeth 11 and driven by chain gearing from a counter-shaft which is operated through a pause-gear by the main shaft 4. The wire is fed from reels 35 to wire-carriers 33, 34, Fig. 10, mounted on a slide 3, Figs. 1 and 10, adapted to be moved axially, towards or away from the ring, by a cam 38 on the main shaft. The slide is kept in contact with the cam by a spring 40. In the ring, there is a segmental opening 26, Fig. 5, through which the wire-carriers can pass when the slide is advanced. The movement of the wire-carriers is limited by the engagement of projections 36 on the carriers with stationary projections 33, Fig. 1, and inclined projection 37, Figs. 1 and 10, on the frame in their forward and backward position respectively. Mounted close to the ring, on the opposite side to the slide 3, is a sleeve 18, open at the back, and adapted to receive the head of the bottle to be wired. Mounted within the ring are a pin 27, for twisting and forming a loop in the wires, and cutters 28. Between the sleeve 18 and the ring is a curved slide 19 with a forked lower end adapted to embrace the wires. This slide is guided by a curved arm 14 springing from the upright 13, and is operated through linkwork 22, 23 by the slide 3 as it moves to the rear. Near the sleeve 18 are a spring-controlled lever 24, adapted to receive the advanced wires and to guide the severed twisted ends from a previous tying close to the bottle neck, and a crank 72, which is journaled in the frame and operated by rack-andpinion gearing, and provided with a bevelled projection 81, Fig. 14, adapted to bend the abovementioned ends beneath the wire which is to encircle the bottle neck, as described below. The main shaft 4 is adapted to be thrown into gear with the driving-wheel 51 by a clutch 57 operated through a rod 6 by the swinging bottle rest 43, when a bottle is inserted in the machine. In operation, after each tying the slide 3 is in its advanced position with the ends of the wirecarriers projecting through the ring. The carriers swing on pins 60 and the side carriers are held apart by their projections 36 engaging the frame. The lever 24 then supports the wires. A bottle is inserted, and the bottle rest 43 swung to a vertical position. The bottle rest forms a bellcrank lever, the lower arm of which acts on tbe rod 6 and causes it by means of a hook 51 to engage a pin 52 and withdraw a weighted swing- ing bell-crank lever 50 from engagement with the clutch 57, so starting the machine. Also, during the first part of the motion, a projection 77, Fig. 4, on the bottle rest engages a projection 78 on an arm hinged at 75 to a vertical rack as shown, and so operates the crank 72 and projection 81 to bend inward the knot of the wire to the dotted position shown in Fig. 14 ; the bottle rest next engages a projection 79 on the lever and so frees the projection 78 from the projection 77 and allows the rack to fall. As the projection 81 is bevelled, the wire is pushed laterally and finally lies as shown in Fig. 15. The slide 3 is then moved backward to stretch the wires around the neck and over the cork, and the slide 19 is operated to embrace all the wires and position them around the pin 27, which just previously is advanced by a slide 16, Fig. 4, operated by a cam 61 on an eccentric 17 on the main shaft. The slide 16 descends by gravity and when the wire-guides have retreated clear of the ring, the latter is rotated a predetermined number of revolutions. The next moment the cutters 28 are advanced, acted upon by a forked portion 30, Fig. 5, of a slide 15 operated by the eccentric 17. The pin 27 is then retracted by a lever 32, Figs. 4, 5, and 7, operated by the continued movement of the slide 15. At substantially the same time, a slide 20 is raised by the engagement of a projection 21 on the cam 61 with a projection 20x on the slide, to press the twisted ends of the wires against the bottle neck. As an alternative to this, the wires may be bent down close to the neck by the lever 19, operated through the lever 22 by cam-like projections 90, 91, Fig. 1, on the disk 57 and lever 22 respectively. The rod 6 is then moved to the left by the cam 38. This swings the bottle rest over and releases the bottle. The hook 51, during the movement of the rod 6 to the right, is carried beneath a cam 95, Fig. 1, which frees the hook from the pin 52 and allows the lever 50 to swing to its normal position ready to re-engage the clutch and stop the machine at the conclusion of the operation. Other means than the chain gearing described may be used for driving the ring. According to the Provisional Specification, the knot-turner may be operated by a rod acted upon by an arm or the like extending from the shaft.
